can anyone offer words of wisdom on how to access the household blade contacts inside the upper barrel of the 2773 battery case. is it a one-piece unit that can be slipped out easily and, if so, how. i took the black plate & the top bulb cap off to have a look-see but couldn't see anyway to get the household socket assembly out. the battery case works, but there seems to be a only sporadic connection when using it to trip the shutter, so something seems to be amiss under the button. there was a gold-colored contact under there. i'd like to dig a little deeper if possible to try to put it to rights in order to get it snapping every time.
also what should be used to clean the contacts?
thanks in advance for any help.
